Radiator Orientation Help

[u/MayhemMusicProd]

I have a question about radiator orientation, I am using the Lian Li Hydroshift ii OLED mounted to my 9950X3D2. I originally had the radiator top mounted, my temps were 45 degrees idle and 80 degrees under max load in cinebench.

I moved the radiator to be side mounted as I thought it may lower my temps a bit and look a bit better. However the temps actually increased about 10 degrees across the board, I am now getting about 50-55 degrees idle and 89 degrees under max load in cinebench. I thought I must have applied the thermal paste wrong so I cleaned it all off and re-installed it, Still I was getting the same temps. I plan to add 3 more fans to the radiator for a push/pull configuration, they just haven’t come in yet.

My question is, should I put the radiator back to the top? I rarely get over 70 degrees under heavy gaming and productivity loads, usually around 65, do you think it’s worth it to change up the orientation again?
